CHARLES MYERS, OF EUGENE, OREGON.

PHOTOGRAPHIC FLASH-LIGHT.

Specification of Letters Patent.

Patented June 27, 1916.

Application filed August 9, 1913, Serial No. 783,939. Renewed May 23, 1916. Serial No. 99,429.

To all whom it may concern Be it known that I, CHARLES MYERs, a citizen of the United States of America, residing in Eugene, in the county of Lane and State of Oregon, have invented certain new and useful Improvements in Photographic Flash-Lights, of which the following is a specification.

This invention relates to an improved flash-light for the use of photographers, and for this purpose the invention consists of a photographic flash-light which comprises a powder-pan, a powder-receptacle below the pan, means for supplying the powder to the pan, electrodes in said pan, a fuse-wire between the electrodes in the pan for igniting the powder therein.

The invention consists further of certain details of construction which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawing, Figure 1 represents a side-elevation, partly in ver-' tical longitudinal section, of my improved photographic flash-light, and Figs. 2 and 3 are side-views of the electrodes screwed into the bottom of the flash-light pan.

Similar reference characters indicate corresponding parts throughout the figures of the drawing.

Referring to the drawing, 6 and 7 represent the electrodes which are screwed through the bottom of the powder-pan 14 so as to project to the interior of the same. The electrodes 6 and 7 are provided preferably with thumb-pieces 16 and 17 at their lower ends and collars 18 up to which the electrodes can be screwed through the bottom of the powder-pan 14. The inner ends of the electrodes 6 and 7 are provided with V-shaped recesses for supporting a fusewire as indicated at 19. The electrode 6 is made larger than the electrode 7, the one serving for connecting with the negative and the other with the positive pole of a battery or other source of electricity 13. To the powder-pan 14 is attached, midway between the electrodes, a flat Vshaped or funnel-shaped body 8 that is supported by its tubular shank 28 in an opening in the bottom of the powder-pan for establishing connection between the powder-pan and a powder-receptacle 10 that is attached to the underside of the pan 14 and filled with magnesium-powder. Alongside of the receptaole 10 is arranged a tube 15 through which the conducting wires from the source of electricity 13 are conducted to the electrodes 6 and A switch 11 is arranged at any suit-able point of the tube 15 so as to close the circuit when a spark between the electrodes 6 and 7 for igniting the powder and producing the flash, is to be transmitted. A follower 12 is arranged in the bottom of the receptacle so as to bring the powder in upward direction and closer to a blowtube 9 which is arranged in the upper part of the receptacle, and by which a sufficient quantity of powder is transferred from the funnel 8 into the pan 1A and thence into contact with the fuse-wire 19. The V- shaped or funnel-shaped body 8 may be made in the required size for permitting the powder to be distributed equally over the same and slightly above the fuse-wire between the electrodes.

The improved flash-light is used by taking hold of the receptacle, closing the switch, and transferring the required quan tity of powder required for a flash by the blow-pipe from the receptacle 10 to the funnel-shaped body. As soon as another flash-light is required, another quantity of powder is discharged from the receptacle by means of the blow-pipe onto the funnelshaped body, and then ignited by the fusewire.

I claim:

1. A photographic flash-light apparatus, comprising a powdenpan, threaded electrodes vertically adjustable in said pan, a supply-funnel between said electrodes pro vided with a tubular shank, a fuse-wire connected with the electrodes and extending between the same and over the supplyfunnel, a powdenreceptacle attached to the bottom of the powder-pan below the sup ply-funnel, a blow-pipe extending into said receptacle, conducting wires connecting the electrodes with the source of electricity, and a switch for closing the electric circuit through the fuse-wire.

2. A photographic flash-light apparatus, comprising a powder-pan, electrodes threaded in the bottom of and extending into said pan, a supply-funnel between said electrodes provided with a tubular shank, a fuse-wire connected with the electrodes and extending between the same and over the supplyfunnel, a powder-receptacle attached to the bottom of the powder-pan below the supply-funnel, a blow-pipe extending into said,

receptacle, conducting Wires connecting the as my invention, I have signed. my name electrodes with the source of electricity, a in presence of tWo subscribing Witnesses. gube running alongside of said receptacle CHARLES MYERS.
